The most arrogant and ****y customer service agent

i took out a new phone with mtn, the iphone 4s and since the day i got it i have been having issues, everytime i try to make a call it says call failed. i was then told to give the phone in, after a few days i get told that they cant work on the phone cos i still had find my iphone activated and that i must deactivate, so i logged in online and did it. few days later i get told that they couldnt do anything and that they are sending it back cos i need to manually deactivate the service. a few days later the phone is supposed to be on the way but still nothing and i was given the repair centre number, enter Tsepo, he answered the call like a normal person, listened to what i had to say and checked the system and said he cant find it please hold while he searches the courier system, in his hushed monotone, he then informs me that its not there and it must be in the warehouse so hes gonna send them an email. so i explain to him i just want to know whats happening cos nobody is telling me anyting definite and he just keeps quiet and i say hello are you going to say anything and he says that hes not going to say anything cos he already told me what he can do, thats it.
